I think he's not acacepting because their young cockerals?

I have one rooster who took his leadership about 2 and 1/2 months ago.He crows,and he makes sure everyone is in their place.

I got a few chicks five weeks ago (Beginning of April.)Now I am almost "POSITIVE" i have at least two roosters.One calls his flock over if he finds something good (Five week olds'!)The other is just aggressive,and has a cherry red combs,and waddles.The other one also has a comb,and some waddle development.

Well Zeus has gotten aggressive the older the chicks got.I'm not sure how he his planning on attack them.He runs at them,will follow them around (Convinced to attack them).Just not sure if he wants to just do the peck and chase,or fling them in the air,or spur them.He has never experienced having chicks in the flock (He was the rooster on the lower totem pole up until I gave the other two away,and he is only a year old.)My other roosters that I gave away was six years,and would never be nearly this aggressive towards 5 week olds. But within 3-4 month olds he had no sham and running them off,pullet or cockeral.

Any idea on how I am gonna integrate them?In about 2 weeks they gotta be out the house,and into the chicken coop (their already half too big for their brooder cage.

I have a few chickens.

2 barreds,named Falcon and Hawk

1 New Hampshire rooster named,Zeus

2 New Hampshire hens named,Vanillipe (One has no name)

1 silver laced Wyandotte named,Special girl

1 White Leghorn roosters named Foggy

3 black&red Sex links,(Black)angel,and one red is named little red,and the other one is Mrs.Prissy

Its very hard to integrate chicks into a pen with a chick-aggressive rooster. At this he likely can't even tell they are roosters and it simply being aggressive to them because they are chicks. Chick-aggressive Roos will pester and even kill chicks and overall are a pain. They are also pretty uncommon. I personally don't tolerate chick-aggressive cocks. They attack me they get two strikes but they even think about going after a chick and they are soup. It's not a good trait to have in any flock rooster.

I would recommend not adding them into the coop with him until they are significantly bigger (10-12 weeks would be a good age) and having them separated within eyeshot for an extended period of time, two weeks minimum but 3-4 weeks or even more would be better given its a rooster being dealt with.

I find this interesting. My roosters have always been excellent, even better than the hens, with accepting both new pullets into the flock (That I can understand.) and they have been good with younger birds, maybe six or seven weeks old that have been penned within sight of the main coop but are being let out to free range. I credit my roosters with making introductions easier. It seems one of the rooster's jobs is keeping peace within his flock.

Maybe you just have a young rooster that doesn't totally understand his job or just doesn't like newbies in which case you need to keep them separate for a while.
